Ross, You are looking too hard! Most of the Elecraft tuners use the same technique - the selected relay is activated and the return path flows through all the rest of the other relay coils - there is not enough current through any one coil to activate them, and it works quite well - one more piece of "magic" that can be done using PICs.
